Hi.
your answer is 6 cm.
hope this helps!!!
The answer would be both. Photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants use both humans use just cellular respiration.
Answer;
- phosphate group
- Ester functional group
- Alkene
- Alkane side chains.
Explanation;
Phospholipids are types of lipids that are major components of the cell membranes.
They consist both the hydrophillic (water loving) and hydrophobic (water hating) ends.
The major functional groups in a phospholipids are;
- the phosphate groups - PO4
- The Ester functional group- - COO-R
- Alkene side chain - -CH=CH-
- Alkane side chain - -CH-CH-
Answer:
Glycine is required for purines, aspartate for pyrimidines, glycine and aspartate for both purines and pyrimidines. The remaining amino acids are not required for the synthesis.
Explanation:
Nucleotides are the monomer for the synthesis of DNA and RNA. The two main class of nitrogenous bases are purines and pyrimidines. These nitrogenous bases require the amino acids as a precursor for their synthesis.
Glycine is the simplest amino acid and required for the synthesis of purines. Aspartate is required for the synthesis of pyrimidines. Glutamine and aspartate are required for the synthesis of both purines and pyrimidines. Lysine, leucine, alanine, histidine, methionine, tryptophan and alanine are not used as a precursor for the nucleotides.
